چکیده
|
This paper studies the finite element (fe) approximation to a second-type variational inequality. the supe rclose and superconvergence results are obtained for conforming bilinear fe and nonconforming eq rot fe schemes under a reasonable regularity of the exact solution u ∈ h 5 / 2 (ω),which seem to be never discovered in the previous literature. the optimal l 2 -norm error estimate is also derived for eq rot fe. at last,some numerical results are provided to verify the theoretical analysis. © 2012 dongyang shi et al.
